Selection of child seats in terms of vibration comfort

Abstract

The article presents the results of laboratory and road tests of the impact of the method of fastening child seats on the vibration comfort of children transported in them. The tested child seats were mounted facing the direction of travel on the rear seat of a passenger vehicle. Two child seats were used in the work, the first (red) was attached to the rear seat behind the driver’s seat using the ISOFIX base. The second child seat (grey) is attached to the rear seat behind the passenger seat with standard seat belts. During the measurements, the child seats were loaded with the mass of 5 kg, 10 kg and 15 kg, simulating the mass of a child fastened in a child seat. The child seats used can be mounted both forward and rearward facing. In the conducted research, they were installed in a passenger vehicle facing the direction of travel. Laboratory and road tests based on registered vertical accelerations showed a negative impact of using the ISOFIX base in terms of vibration comfort.
